三角脉冲载荷作用下黏弹性浮冰的瞬态响应
摘要
Abstract
The multi-partition function of triangular pulse was represented with a whole function ac-cording to the Heaviside unit-step function.The dynamic equation of floating ice plate under triangu-lar pulse load was solved through the Hankel transformation and the Laplace transformation.The function of response and numerical calculation results of transient response of floating ice plate under triangular pulse load were obtained.The influences of geometrical parameters of floating ice plate, physical parameters of floating ice plate and the reservoir depth on the displacement response were an-alyzed.Various dynamic properties of floating ice plate due to the coupling of floating ice and water were revealed.The experiment results show that the calculation results agree with the experimental data,which is proof of the effectiveness and rationality of the calculation method.关键词
